Description

Technical Field

[0001] This utility model relates to the field of pelleting machine technology, and in particular to a filtration device for condensate in pelleting machine and a pelleting machine. Background Technology

[0002] In the process of making popping beads, the popping bead machine is the main piece of equipment, and its circulating condensate plays a crucial role, enabling the popping beads to cool and solidify rapidly. However, over long-term use, the circulating condensate inevitably becomes contaminated with various impurities, such as suspended particles, moisture, and pigments. The presence of these impurities not only affects the quality of the popping beads but may also cause malfunctions in the popping machine, reducing production efficiency. Currently, existing filtration devices are often single-function and cannot comprehensively and effectively remove impurities (including suspended particles, moisture, and pigments) from the circulating condensate, resulting in a decrease in popping bead quality. Utility Model Content

[0003] The purpose of this invention is to solve the problem that existing filtration devices cannot effectively remove suspended particulate matter, moisture, pigments, and other impurities from condensate, thus reducing the quality of popping beads. This invention provides a filtration device for the condensate of a pelletizing machine and a pelletizing machine itself, which can specifically remove suspended particulate matter, moisture, and pigments from the condensate, thereby improving the purity of the condensate and ultimately improving the quality of the popping beads.

[0004] To solve the above-mentioned technical problems, the present invention discloses a filtration device for the condensate of a pelletizing machine, comprising:

[0005] The box has a partition plate that divides the inner cavity of the box into a first receiving cavity and a second receiving cavity. The side wall of the box has a liquid outlet that communicates with the second receiving cavity.

[0006] A filter assembly is disposed in the first receiving cavity, and the filter assembly is used to filter the condensate input into the first receiving cavity;

[0007] A water removal component is disposed in the second receiving cavity. The water removal component includes a holding box and multiple silica gel particles disposed in the holding box. The bottom of the holding box is spaced a certain distance from the bottom of the second receiving cavity. A first opening is provided on the top of the holding box. Multiple first through holes are provided on the holding box. The silica gel particles are used to absorb water in the condensate.

[0008] An infusion pipeline is equipped with a power pump. The inlet end of the infusion pipeline is located in the first receiving cavity, and the outlet end of the infusion pipeline is located above the first opening. The infusion pipeline is used to transport the condensate in the first receiving cavity to the water removal assembly.

[0009] The pigment removal component is located below the water removal component. The pigment removal component includes a container and activated carbon in the container. The container has a second opening at the top and multiple second through holes. The activated carbon is used to adsorb pigments in the condensate. The bottom of the container is higher than the liquid outlet.

[0010] During use, the condensate enters the filter assembly, which filters out particulate impurities from the condensate. The condensate after removing particulate impurities flows into the bottom of the first receiving chamber, and then is drawn into the dehydration assembly through the infusion pipeline and power pump. Silica gel particles remove moisture from the condensate. After dehydration, the condensate flows into the pigment removal assembly below, where activated carbon adsorbs pigments from the condensate, thus completing the removal of particulate matter, moisture, and pigments.

[0011] By adopting the above technical solution, suspended particles, water and pigments in the condensate can be removed step by step, thereby improving the purity of the condensate and thus improving the quality of the popping beads.

A sealing strip is provided on the outer wall of the housing and surrounds the notch. A locking element is provided between the baffle and the outer wall of the housing. The locking element is used to press the baffle against the sealing strip when the baffle comes into contact with the sealing strip and to lock the position of the baffle.

[0017] Optionally, a support frame is provided inside the second receiving cavity, and two slides are provided on the support frame.

[0018] Optionally, the silica gel particles are color-changing silica gel particles, which change color after absorbing water.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0034] like Figure 1 , Figure 2As shown, this utility model discloses a filtration device 100 for the condensate of a pellet-making machine, comprising: a housing 110, a filter assembly 120, a water removal assembly 130, and a pigment removal assembly 150. The housing 110 is made of food-grade stainless steel to ensure the condensate is not contaminated. A partition plate 111 inside the housing 110 divides the inner cavity into a first receiving cavity 112 on the left and a second receiving cavity 113 on the right. An outlet 114 communicating with the second receiving cavity 113 is provided on the side wall of the housing 110. The first receiving cavity 112 serves as a coarse filtration zone, and the filter assembly 120 is installed inside to filter suspended particulate matter from the condensate entering the first receiving cavity 112. The second receiving cavity 113 serves as a fine treatment zone, and the water removal assembly 130 and the pigment removal assembly 150 are installed in upper and lower layers. The dehydration assembly 130 includes a container 131 and multiple silica gel particles (not shown in the figure for easy viewing of the first through-hole 133 at the bottom) disposed within the container 131. A certain distance is spaced between the bottom of the container 131 and the bottom of the second receiving cavity 113. A first opening 132 is provided at the top of the container 131, and multiple first through-holes 133 are provided at the bottom of the container 131. The silica gel particles are used to absorb moisture from the condensate. For example, the container 131 is barrel-shaped with a circular bottom. The inlet end of the infusion pipe 140 is located within the first receiving cavity 112, and the outlet end of the infusion pipe 140 is located above the first opening 132. A power pump 141 is also provided on the infusion pipe 140. The infusion pipe 140 is used to transport the condensate in the first receiving cavity 112 to the dehydration assembly 130, so that the condensate after particulate removal undergoes dehydration treatment. Specifically, the power of the power pump 141 is adjustable to regulate the condensate delivery speed. The pigment removal component 150 includes a receiving box 151 and activated carbon disposed in the receiving box 151. The activated carbon is used to adsorb pigments in the condensate. A second opening 152 is provided at the top of the receiving box 151, through which the condensate after being dehydrated by the dehydration component 130 enters the receiving box 151. The bottom of the receiving box 151 is higher than the liquid outlet 114, and the bottom of the receiving box 151 is provided with a plurality of second through holes (not shown in the figure), through which the pigment-removed condensate falls into the bottom of the second receiving cavity 113. Exemplarily, the receiving box 151 is drawer-shaped. The diameters of the first through hole and the second through hole are equal.

[0035] In use, the condensate enters the filter assembly 120, which filters out particulate impurities from the condensate. The condensate after removing particulate impurities flows into the bottom of the first receiving chamber 112, and then is drawn into the dehydration assembly 130 through the infusion pipe 140 and the power pump 141. Silica gel particles remove water from the condensate, and then the dehydrated condensate flows into the pigment removal assembly 150 below, where activated carbon adsorbs pigments from the condensate, thereby completing the removal of particulate matter, water, and pigments.

[0036] By adopting the above technical solution, suspended particles, water and pigments in the condensate can be removed step by step, thereby improving the purity of the condensate and thus improving the quality of the popping beads.

[0037] Optionally, such as Figure 3 As shown, the filter assembly 120 includes a first filter funnel 121, a second filter funnel 122, and a third filter funnel 123 arranged sequentially from the inside out. Each of the first filter funnel 121, the second filter funnel 122, and the third filter funnel 123 has an opening at its top (denoted as the third opening 1212, the fourth opening 1222, and the fifth opening 1232, respectively). The first filter funnel 121 is inserted into the second filter funnel 122 through the fourth opening 1222, and the second filter funnel 122 is inserted into the third filter funnel 123 through the fifth opening 1232, allowing for easy removal of any one of the filter funnels through the openings. The first filter funnel 121, the second filter funnel 122, and the third filter funnel 123 have the same cross-sectional shape, which can be circular or rectangular. For example, as shown... Figure 3 As shown, the cross-sectional shape of the first filter funnel 121, the second filter funnel 122, and the third filter funnel 123 is rectangular. Furthermore, the first filter funnel 121 has multiple first filter holes 1211, the second filter funnel 122 has multiple second filter holes 1221, and the third filter funnel 123 has multiple third filter holes 1231. The diameters of the first filter holes 1211, the second filter holes 1221, and the third filter holes 1231 gradually decrease, thereby achieving sequential filtration of large, medium, and small particles. The applicant has discovered that the filtration effect is best when the diameter of the first filter hole 1211 is 5 mm, the diameter of the second filter hole 1221 is 1.5 mm, and the diameter of the third filter hole 1231 is 0.2 mm.

[0038] Furthermore, such as Figure 2 and Figure 3 As shown, the bottom of the first receiving cavity 112 is provided with a support leg 115, and the filter assembly 120 is located above the support leg 115, so that the filter assembly 120 is spaced a certain distance from the bottom of the housing 110, thereby facilitating the smoother flow of condensate from the bottom of the filter assembly 120.

[0039] Optionally, such as Figure 1 and Figure 2 As shown, the second receiving cavity 113 has a notch 1131 on its side wall, and the second receiving cavity 113 has two notches along the first direction (e.g., Figure 2 The slide 117 extends in the X direction (as shown in the middle X direction), with the first direction perpendicular to the plane where the notch is located. The two slides 117 extend in a direction perpendicular to the first direction (as shown in the middle X direction). Figure 1(As shown in the Y direction) The receiving box 151 is slidably mounted on two slide rails 117. The receiving box 151 can slide at least partially to the outside of the housing 110 through the notch to facilitate the replacement of the activated carbon inside the receiving box 151. In addition, the slide rails 117 can reduce the resistance when the receiving box 151 moves, thereby reducing wear and increasing the service life of the receiving box 151.

[0040] Optionally, such as Figure 2 As shown, a baffle 153 is provided at one end of the housing 151 near the notch 1131. The baffle 153 is located outside the housing 110, and its area is larger than that of the notch 1131 to completely cover it. A sealing strip 118 is provided on the outer wall of the housing 110, surrounding the notch. For example, the sealing strip 118 is an automotive-grade sealing strip to improve the sealing effect. A locking member is provided between the baffle 153 and the outer wall of the housing 110. The locking member is used to press the baffle 153 against the sealing strip 118 when the baffle 153 comes into contact with the sealing strip 118, and to lock the position of the baffle 153. For example, the locking member can be a magnet 119 or a bolt to ensure a tight connection between the baffle 153 and the side wall of the housing 110 to prevent condensate leakage.

[0041] Optionally, such as Figure 2 As shown, a support frame 190 is provided inside the second receiving cavity 113, and two slides 117 are provided on the support frame 190. The support frame 190 allows a certain gap between the bottom of the receiving box 151 and the bottom of the box body 110, so that the condensate in the receiving box 151 can flow out smoothly. Furthermore, there is a gap between one side of the support frame 190 and the partition plate 111, so that the condensate flowing out from the second through hole can be evenly distributed at the bottom of the second receiving cavity 113, which facilitates its smooth flow out from the liquid outlet 114 later.

[0042] Optionally, the silica gel granules are color-changing silica gel granules, which change color after absorbing water, thus prompting the operator to replace the silica gel granules. Furthermore, the color-changing silica gel granules are stored in a non-woven bag (not shown in the figure), allowing all silica gel granules to be removed at once during replacement, improving efficiency.

[0043] Optionally, such as Figure 1 and Figure 2 As shown, a mounting plate 180 is provided inside the second receiving cavity 113. The mounting plate 180 is connected to the partition plate 111 and seals the top of the second receiving cavity 113. The container 131 is fixed inside the second receiving cavity 113 by the mounting plate 180. Specifically, the top edge of the container 131 is fixed to the mounting plate 180 by welding.

[0044] Optionally, such as Figure 1As shown, it also includes an inlet pipe 160 connected to the side wall of the housing 110. The outlet end 162 of the inlet pipe is located above the filter assembly 120 to prevent condensate from being directly drawn into the second receiving cavity 113 without being filtered by the filter assembly 120, thus causing incomplete condensate filtration. The outlet 114 is located near the bottom of the housing 110 so that even when there is little condensate at the bottom of the second receiving cavity 113, it can be smoothly discharged from the outlet 114.

[0045] like Figure 4 As shown, this application also discloses a pelletizing machine 200, including the aforementioned filter device 100 and a condenser tank 210. The condenser tank 210 is positioned higher than the filter device 100 and is used to hold condensate. The condenser tank 210 has an inlet 211 and an outlet 212. The inlet end 161 of the liquid inlet pipe is connected to the outlet 212, and is used to transport the condensate to be filtered in the condenser tank 210 to the filter device 100. The filter device 100 also includes an outlet pipe 170. The first end 171 of the outlet pipe is connected to the outlet 114, and the second end 172 of the outlet pipe is connected to the inlet 211. The outlet pipe 170 is used to return the condensate filtered by the filter device 100 to the condenser tank 210 for reuse. Furthermore, since the filter device 100 is positioned lower than the condenser tank 210, a water pump (not shown in the figure) can be installed on the outlet pipe 170 to assist the condensate in flowing back to the condenser tank 210.

[0046] The filtration device and dropper provided by this invention can remove suspended particles, water and pigments from the condensate in a targeted and step-by-step manner, thereby improving the purity of the condensate and thus improving the quality of the popping beads.

[0047] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
